SPECIFICATION forming part of Letters Patent No. 440,051, dated November4, 1890.

' Application filed June 11, 1889. Serial No. 313,950. (No model.)

To aZZ whom it may concern:

Be it known that I, ERNEST W. NAYLOR, a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Punching and Flanging Machines;and I do hereby declare that the following is a full, clear, and exactdescription of the in: vention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, in which- Figure 1 represents a sideelevation of my improved machine, the dies and clampinghead being shownin section in their depressed position. Fig. 2 is a top plan of theentire machine. Figs. 3 and t show, respectively, side elevation and topplan of the machine when used for flanging sheets of large dimensions.Fig. 5 represents averti'cal section on the line a: 00 of Fig. 1,showing the female die raised and the manner of connecting theclamping-head and female die to their respective rams. Fig. 6 is a planof the platen to which the female die is attached. Fig. 7 is a similardetached view of the female die. Fig. 8 is a section on the line y 3 ofFig. (5. Fig. 9 is a top plan of the clamping-head, showing the pointsof attachment of the clampingplungers. Figs. 10 and 11 show the mannerof attaching the punches to the plungers when the machine is used forpunching, and Figs. 12 and 13 represent detail views of the dieguideshown in Figs. 3 and 4.

My invention relates to that style of punching and Hanging machineadapted to be operated by hydraulic rams or plungers. Its object is toprovide a machine of the character described which may be used eitherfor punching or fianging, or for both punching and flanging; also, toprovide a machine adapted for operating on either large or small plates.

To these ends my invention consists of one or more vertical rams forclamping the work to the anvil, and two or more vertical rams foroperating the movable die, and also in a horizontal ram carrying a dieor punch for finishing the turned-down edge.

It also consists in hinged standards at one end of the machine adaptedto assume a horizontal position to permit of the insertion of very largesheets of metal; also, in minor details of construction and combinationsof parts, which will be hereinafter more fully described, and distinctlypointed out in the speci fication and claims.

In the drawings, A represents the upper and A the lower girders of theframe, which are supported and held apart by means of four standards orpillars G G and G G, the

former of which are hinged at c e to the lower girder A and adapted tobe disconnected from the upper girder, as will hereinafter more fullyappear.

In order to strengthen the frame when the machine is operating on verylarge material the upper and lower girders A A are connected by anintermediate brace A at the end having the rigid standards. In the uppergirder A are mounted three or more hydraulic cylinders O B G, placedside by side in a vertical position. In the present machine I have showntwo rows of such cylinders, and on the lower girder is suitably mountedan anvil-block I-I, upon which the metal to be operated on is clamped bya clamping-head I, carried at the ends of the plungers B B of thecylinders B B. To the ends of the plungers C C O C of cylinders C CO 0,located on opposite sides of the cylinders B B is secured a platen J, towhich the female die K is secured, suitable openings j being formed insaid platen for the passage of the plungers B B, carrying theclamping-head I. The

clamping-head and die platen are secured to their respective plungers bymeans of countersunk bolts g.

In order to adapt the machine for operating upon material of largedimensionslhinge the standards G G to the lower girder at the points ee, the upper or free ends of said standards being connected by a rigidcross-head L, the upper girder A being provided with open slots ornotches a forthe reception of the standards or pillars G G, thestandards being screw-threaded above the girders for the reception ofclamping-nuts g, by which the standards are held in place in the uppergirder.

On the standards G G is a sliding cross-head M, which is capable ofadjustment thereon by means of a screw F, journaled in the rigidcross-head L and having collars Z Z to prevent longitudinal movement ofthe screw. A block N, carrying a centering-pin a, is mounted in aguideway in the adjustable cross-head M, and is laterally adjustabletherein by means of a screw E, secured at its ends in said crosshead. Inorder to finish the flange either by corrugating or punching I provideahydraulic ram D on the lower girder, the plunger of which carries atits end a punch or other finishing-tool D, secured thereto, as shown inFigs. and 11.

In Figs. 3 and 4, Ihave shown my improved machine as operating on largesheets having a regular curve, in which case it is desired to flangeonly one edge. In this case I prefer to dispense with the plungers C G,as shown, and secure the clamping-head to only one of the plungers B andthe die to the remaining plunger B, a guide-bracket 0 being used forguiding the die K, as shown in Figs. 3 and 4.

The operation of the machine is as follows: Assuming that it is desiredto flange a sheet of metal on all. sides of a shape corresponding tothat shown in Fig. 6, the proper die and clamping-head are secured tothe plunger, and the anvil-block H of the desired form is secured to thegirder. The metal to be operated on is placed on the anvil-block and theclamping-heads descend upon it. The platen and die K then descend uponthe projecting edge and bends the same, when the clampinghead-and dieare again raised.

When it is desired to flange or bend a large plate which could nototherwise be operated upon except in a press of very large size, thenuts on top of pillars G G are loosened, and the pillars are thenlowered down into suitable adjustable stands or rests P into either ahorizontal or angularposition, thus leaving one end of the pressentirely free and open, and any sized plate can then be inserted andoperated upon.

If it is desired to produce a flange of regular curve and of largeradius, then the plate is centered or attached to the centering-pin onsliding cross-head M, which is moved in one direction by the screw F andin a direction at a right angle thereto by a similar screw E on theslide itself. The plate can then be adjusted as to distance from the dieand true radius found either at one or more heats, accordingly as theflange desired is large or small, and if the desired flange takes anirregular curve the distance may be varied at will to form the curves asdesired. A number of holes may be punched either ina circle or straightline by this device, either in the flange by the ram D or on the body ofthe plate by the vertical rams, by simplyremoving the forming-dies andattaching a punch or punches to the plungers, as shown in Figs.

10 and 11. Where only a single flange is desired or a flange on one sideonly, I prefer to secure the clamping-head to only one plunger B and thedie to the remaining plunger B, in which case I make use of averticalguide 0 for the die K, an opening Q being left in the lower portion ofsaid guide for the passage of the plunger of ram.

While I have shown and described the die as operated on by four plungersand the clamping-head by two,I do not wish to be confined thereto, asmore or less may be used for each without departing from the principleof my invention. The object of the rain D is to square up, corrugate,indent, or otherwise operate on the plates or sheets while held by anyof the vertical rams.

Having described my invention, what I claim,and desire to securebyLetters Patent, 1s-

1. A metal-forming machine having rams provided at their ends withdevices to act upon the metal and having hinged pillars arranged toengage the cross-head in which the rams are mounted, substantially asand for the purpose described.

2. In a metal-forming machine, the combination, with power-actuated diesfor forming the metal, of two hinged pillars adapted to assumesubstantiallya horizontal position, an adjustable cross-head on saidpillars, and a centering-pin adjustable on said cross-head,substantially as and for the purposes described.

3. The combination, ina metal-forming machine, of the movable andstationary dies, an adjustable cross-head carrying an adjustablecentering-pin, and arms pivoted at one end to said centering-pin andadapted to be connected at their other ends with metal to be operatedon, whereby said metal may be moved about a given center, substantiallyas and for the purposes described.

4. In a metal-forming machine, the combination, with the frame composedof upper and lower girders rigidly connected together .at one end, ofpillars hinged to' the opposite end of the lower girder and adapted toengage open slots in the upper girder, and clampingnuts on said pillars,substantially as and for the purposes described.

In testimony that I claim the foregoing improvement in punching andfianging machines as above described I have hereunto set my hand this7th day of June, 1889.
